What relational term is used if a radiographic projection employs a superior tube angle?

• A. Distal
• B. Caudal
• C. Cephalic
• D. Proximal

Answer: (C)

When describing radiographic projections, we use directional terms to show where the beam or part is oriented relative to the body. A superior tube angle means the x-ray beam is directed toward the head. The term for that headward direction is cephalic (often written cephalad). So this projection is described as cephalic/cephalad. Caudal means toward the tail or feet, which is the opposite of a superior angle. Proximal and distal refer to a limb’s closeness to the trunk or to its far end, not to the headward tilt, so they don’t describe this projection correctly.
